References to imagecache module in D7 code

The image module in D7 core handles everything that was done by the imagecache module in D6. This code still references the imagecache module, and needs to be updated. An example:

 if (in_array($form_id, array('imagecache_ui_preset_form', 'imagecache_ui_action_form', 'imagecache_ui_preset_flush_form', 'imagecache_ui_preset_delete_form', 'menu_icons_admin_settings'))) {
    $form['#submit'][] = 'menu_icons_css_generate';
  }
